METAL EXTENSION-SLIDE Y FOR TABLE S.

Specification of Letters Patent.

Patented .Tune 2, 1908.

Application filed February 28, 1907. Serial No. 359,818.

To all whom 'it may concern:

Be it known that I, GoTLoB II. WELTER- LIN, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and useful Improvement in a Metal Extension- Slide for Tables, of which the following is a specification.

This invention relates to extension slides for tables, and more particularly to metal extension slides, the object being to form an extension slide out of galvanized iron, so that it will not be effected by the weather, thereby overcoming the dilliculties now existing of the slides swelling and jamming in damp climates.

Another object of my invention is to provide an extension slide out of sheet metal, which is very simple and cheap in construction and one which is very effective in use.

IVith these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts hereinafter fully described and pointed out in the claims.

In the drawing forming a part of this specification:-Figure 1 is a perspective View of my im roved slide attached to the side rail of a ta le. Fig. 2 is a sectional view of the slide and a portion of the table. Fig. 3 is a perspective View of one of the slides detached.

Referring to the drawings A, A and A2 indicate the duplicate interlocking slides, the slides AQ A2 of which are secured to the end of the table-frame, in the ordinary manner, and the slide A to the side-rail of the table E, as will be hereinafter fully described.

The slides are formed of rectangular casings having longitudinal slots B formed in their sides by splitting the sides centrally, and bending the sides inwardly and back upon themselves as shown at BQ forming a guideway. The opposite sides of the casings are bent centrally and inwardly, as shown at B2 forming a longitudinal groove in which is secured by rivets, a U-shaped member O, provided with flanged ends C which are bent back upon themse ves at C2 forming guidemembers which are adapted to work in the guideways of the adjacent casing, the guidebearing against the bent back portion of the sides, forming a tight slide. Blocks B are secured in the member C adjacent each end reinforcing the members so as to hold them rigid without any danger of them giving and' jamming the slides.

The casing A is riveted to an angle-plate F secured to the side-rail of the table, and the guide-ends of the member C carried by the casing are also riveted to the angle-plate which securely fastens the slide to the table and su port.

I-Iavm@ thus fully described my invention,

what I c aim as new and desire to secure by Letters Patent is Extension table slides comprising hollow casings, guide-ways formed in one side of certain of said casings by slitting said side longitudinally and bending back upon themselves the edges of said side along said slit,

llongitudinal grooves formed in the opposite side of certain of said casings by bending the side inwardly, and U-shaped members secured. in said grooves and provided with flanged ends having their edges lbent back upon themselves, certain of said U-shaped members being adapted to slidingly engage certain of said guideways.
